application inea .epm 11,

To @ZZ whom i may concern Be it known that we, FRED L. 'WARNER andULYssrs G. Rises, citizens of the United States, and residents of Onawa,in the county of lilonona. and State of Iowa, have invented certain newand useful Improvements in Antiskid l/Vheel Attachments, oil which thefollowing is a speciication.`

Our. present invention contemplates an improved anti-shieldingattachment for mo-` tor vehicles adapted to be controlled from thedrivers seat.

Another object of the invention isfthe production of an anti-shieldingattachment for vehicle wheels which is simple and inexpensive inconstruction, comparatively light in weight and thoroughly eiiicient anddependable.

These and other objects and advantages we successfully attain in theembodiment hereinafter described, deiined in the append-y ed claims andillustrated in the accompanying` drawings which form a part ot' thisapplication and in which like characters of reference indicatecorresponding parts throughout the several views, of which,-

Fig. 1 is a iragnientary, longitudinal, vertical section ci a motorvehicle 'equipped with the preferred embodiment ot. the invention.

F ig. 2 is a fragmentary plan oili the saine.

Fig. 3 is a rear elevation ol one of the road-engaging elements and thedevices associated therewith, parts `being cut away and shown insection.

Figa is a side elevation ot Fig. 3, and

Fig. 5 is an enlarged plan of one of the road-engaging element supporthousings and associated parts shown in section.

Although we have illustrated and hereinafter described but oneembodiment oi' the invention, we would not be understood as beinglimited to such specilic structure for various alterations andmodiiications may be made in details of construction and arrangement ofparts without departing from the spirit and scope of the invention asdefined in the appended claims.

`lletei-ring, now, to thc illustrations., li repn resents the main trameoi' a motor vehicle, 'T the rear axle housing', S one of the rearwheels. 9 the spokes er' the wheel, 10, the brake drum Carried by thewheel, and 11, the brakel drum housing or other element, :freelyencircling the brake drum carried by the rear axle housing and adaptedto co- 1322. Serial No. 551,700.

operate with our device, vas will presently appear. We provide a collar,12, which freely encircles the brake drum housing, 11, or itsequivalent, and is connected by spider arms, 13, with a suitable collar,14;, slidably mounted on the rear axlek hub. The side of the collar, 12,adjacent the wallis externally beveled, as at?, leaving'a comparativelynarrow peripheral iace, 28, on the collar, which is parallel with theaxis 0f the4 collar.

lt will be understood that each rear wheel is provided with ourequipment, but inasmuch as .the equipment of each wheel isv a replicaoit the other we have deemed it necessary to illustrate but oneequippedwheel, and it will be understood that on each` end portion ofthe'axle housing, 7, is mounted one ont thecollars, 14.

rlhe collar, 12, is movable toward and from the wheel and preferablybetween `the element, 11, and the collar are interposed anti-irictiondevicesy as the ball bearings7 15, whereby pressure on the*road-engaging elements is imparted to the element, 11,-

without interfering` with longitudinal movement ot the collar, 12. y

The road-engaging meansWhich we employ consists ofa series of,elongated, radially disposed members, extensible and retractable to andfrom road-engaging positions and carried by the wheel.- ln theembodiment chosen igor illustration we secure tl e` road-engaging'elements to the'spolres of the wheel by means ot supporting blocks,

16, which project from the inner tace ot ther wheel and are providedwith semi-circular recesses, `17, which receive the spoles,"9, the saidblocks being suitably secured to the spokes as by clamps, 18, positionedon the outer sides of the spokes and carrying stub bolts, 19, projectingthrough ears` 20, on the blocks, and firmly clamping the blocks to thespokes by means of nuts, 21, screwed on the said bolts and into lirmengagement with the ears, Q0. To prevent rotary movement olr thesupporting elements, 16, from the spokes we provide on the ends of suchelements projecting lips, which are spaced 'to conform to and engage theside oil the telly., 2B. olE the wheel. The elements, 16n are providedwith longitudinal chambers, 24, and the respective ends ot the elements,16, are provided with aligned openings, 25, communicating with thechamber. Q4. EX-

tending` through the openings, 25,- and the" chamber "24, are flat-sidedroce-,26, the openings, 25, being also flat-sided to prevent rotarymovement or" the rods. The inner ends of the rods, 26, are engaged withthe periphery face, 27, of the collar, 12V, and are preferably providedwith anti-friction devices, as the balls, 29, which reduce the trictionbetween the collar and rods. The outer end portions of the rods, 26, areoffset, as at 30, from the wall to extend adjacent the side ofthe tire,31. The ends of the rods, 26, are engageable with the road and arepreferably beveled to a chisel point, 32. The rods are heldyieldablyretracted `lrom road-engaging positions as by compression springs, 33,encircling the rods, 26, within the chambers, 24 and interposed betweenthe outer ends or the supporting blocks, 16, and bosses5 34, on therods.

It is now clear that by shitting of the collar, 12, toward and from thewall the beveled face thereof accordingly co-acts with the rods to forcethem outwardly to road-engaging position and permits them to beretracted from road-engaging positions through the action `of thesprings, 33.

These devices with which each rear wheel is equipped, as previouslystated, are oontrolled by any preferred means, preferably bell-cranksfulcrumed, as at 35, on suitable bearings, 36, mounted on opposite sidesof the center oit the axle housing, 7, the arms, 37, of said bell-cranksbeing connected by suitable links, 38, with the collar, 14. The

arms, 39, of said bell-cranks cross each other and are suitablypivotally secured, as at 40, to one end of a link, 41, the opposite endor which is connected, as at 42, to a suitable lever, 43, fulcrumed, asat 44, on a quadrant, 45, suitably supported by the main trame or otherixed part of the vehicle, the said lever, 43, being provided with apawl, 46, engageable with the quadrant. By virtue of this structure nowdisclosed, movement of the lever, 43,`in one direction forces thecollars, 12, in the direction of their associated wheels to extend theroad-engaging elements, 26, while movement oic the lever in the oppositedirection permits the said roadengaging elements to retract. lt willalso be evident that the lever may be operated to extend theroad-engaging elements to and hold them in intermediatey or partiallyextended positions.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent of the United States, is,

1. An anti-skidding attachment for a vehicle wheel embodying supportingmembers suitably secured to the side of the wheel, radial rods slidablethrough the said mem- `bers to and 'from road-engaging positions,

means within said members holding the rods yieldably retracted fromroad-engaging positions, a bevel-faced collar movable toward and fromthe wheel, antidriction members on the inner ends off the rods andengageable by the beveled tace of the collar, whereby movement of thecollar toward the wheel extends the rods to road-engaging positions, andklever-controlled means for the control of the collar. v

2. An anti-slridding attachment for a vehicle wheel having an axlehousing and circular memberl carried thereby coaxially therewith,`comprising a bevel-laced collar encircling said member, anti-frictionballs between the collar and saidy member, elongated radial rodscarriedby the wheel and extensible and retractable to and fromroadengaging positions, anti-friction balls on the inner ends of therods engageable with the bevel face or the collar, the collar beingmovable toward and 'troni the wheel to accordingly coact with the latterballs to extend4 the rods and permit them to be retracted, means Jforretracting the rods, and means for the control of the collar.

ln testimony whereof, we have hereunto set our hands this 28th day ofMarch, 1922.
